Application fil ed my 24, 1925. Serial m. 45,313..

This invention relates to an improved latch for closures, having moreparticular reference to a closure which is especially, but notnecessarily, desi ned for use in connec- 6 tion with swinging doors andthe like.

Briefly, the invention resides in the revision of a pivotally mountedlatch of right angular formation, wherein one arm is constructed forcooperation w1th a keeper and the other arm for connection with a springressed slidably mo-unted shaft carrying and knobs for pulling andpushing the shaft for actuating the latch. A pivoted ie taineri'sprovided for cooperation with the latch to hold it against pivotalmovement to prevent operation of the improved device whenever necessary.

The invention is characterized particularly by the pull and pushactuation, the arrangement being such that when it is desired to openthe closure from the outside,- the outside knob is simply pulled,whileto open it from the inside, the same is merely pushed.- ,Othe1features and advantages of thevinvention will become apparent from thefollowing description and drawing.

In the accompanying drawing formin a part of this application and inwhich like numerals are employed to designate like parts throughout thesame:-

Figure 1 is a fragmentary sectional and" elevational viewshowing adevice con,-

structed in accordance with the present in vention with the latch in alocked state.

Fi 2 is a detail section taken approximate y upon the plane of the line22 of Fl%. 1- j ig. 3 is a view similar to Fi 2, but taken at asubstantial right angle thereto.

a In the drawin it is to be assumed that the device,-as be ore, stated,is applied toa horizontally swinging door which is indi- 'cated by thereference? character 1.- The frame is represented by the referencecharacter 2, and it will be noted that this frame is provided with arecess 3 formin a keeper seat, adjacent which, is a base p ate 4 havinga portion extending over part of the recess to provide a shoulder. Onthe inner side of the door is a bracket 5 including a pair ofspaced/ears between which the cen-' tral portion of a latch 6 ispivoted. The

latch, as previously stated, is of right angular formation and one armis provided with a nose 7 for cooperation with the aforesaid shoulderand keeper socket.

j The other arm is detachably pivoted as at 8 to the enlarged portion-ofa sliding shaft 9. Said arm may be provided with an elongated slot toaccommodate the pivot 8 there- .by permitting sufficient lateral playaround the ivot to eliminate any possibility of bindln This shaft isprovided at its oppo- 1 site en s with knobs 10 and 11 respectively.

The door 1 is provided with a bored opening in which a metal socket 12is arranged. This socket is provided on its outer end with a spacingplate 13. A spring is confined within this socket and is connected witha shaft .9 in a manner to hold it in the approximate position shown inFig. 1, at which time the latch 6 will be caught. s In order to maintainthe latch in the last named position, a' pivoted retainer 15 isprovided. This retainer comprises a strip of metal -havin ne endprovided with a right. 'a'ngular nger piece-lfland the other endprovided-with a verticalright angular wedge l7 aillapted-to be-locatedbehind the adjacent an of the latch to hold it in closed position/asshownin Fig. 1. i

It iS/Obvi'us th twhen the .fingerpiece 16 is p'ressed downwardly, theretained-15 is rocked abo 1 t its pivot ina manner to move the wedge17({0 inoperative position. Now,

by pushmg utwardly on the inside. knob 10, the latch n to release thedoor. Furthermore by pulling outwardly on the outer knob 11 when on theoutside of" the door, the same action will take place.' The coiledspring, however, will re turn the. arts to normal locking position.

, will be rocked upon its pivot A care 111 consideration of thedescription I in connection with the drawings will un- Y doubtedlysuffice to enable persons skilled in the art to which the inventionrelates to obof one of the armsof the latch having a nose tain a clearunderstanding of the same.

tive ends of the shaft, the free end of the other arm of the rightangular shaped latch ,being pivotally secured to the shaft adjacent theinner end thereof, a coil spring associated With the shaft and with saidclosure for holding the shaft in a predetermined position, the lastmentioned arm of the right angular shaped latch having a notch formedinthe edge thereof, a lever pivotally supported intermediate its ends onthe inner side of the door, a Wedge shaped-member formed on one end ofsaid lever and adapted for cooperation with said notch for holding thelatch in a lockedposition, and a handle asactuating the same to permitthe disengagement of the Wedge shaped portion from the notch.-

In testimony whereof I afiix my signature.
